CLOCK-SETTING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 639,587, dated December 19, 1899.

Application filed May 19,1899. Serial No. 717,397. (No model.)

To all whom it may concern.-

Be it known that I, ALMERON M. LANE, a citizen of the United States, residing in Meriden, in the county of New Haven and State of Connecticut, have invented certain new i and useful Improvements in Clocks, of which the following is a specification.

My invention relates to improvements in clocks; and the objects of my improvement are simplicity in construction and convenience in operation of the pointer-setting device with reference to a bell mounted on the back of the clock.

In the accompanying drawings, Figure 1 is a rear elevation of my clock. Fig. 2 is a sectional View, partly in elevation, of so much of said clock as is necessary to show my improvements, the plane of section being indicated by the line 00 00, Fig. 1. Fig. 3 is a rear elevation of parts of the same with the bell removed and the pointer-setting shaft being shown in transverse section.

The main parts of the case A and movement may be of any ordinary construction. The back B of the case is in the form of a flanged plate adapted to iit into the back of the case and to be detachably secured thereto by means of the spring-latches 4, in accordance with a prior invention of mine. The said back also constitutes one of the movementplates, and to which the ordinary posts or pillars 7 are secured, the other movementplates 5 and 6 being also connected with the same posts or pillars 7.

The center shaft 8 has its bearings in the movement-plates 5 and 6 and passes loosely through the back B without being in bearing contact therewith and is provided at its rear end, outside of the said back, with a pinion 0,

which may be secured in any proper manner- ,f as, for example, by means of the bent pin or Wire 10, Fig. v Adjacent to the center shaft,

- but a little to one side thereof, I secure the bridge or two-armed standard 11 to the back, preferably by means of rivets 12. The said bridge 11 serves the double function of a standard for the bell 13 and a bearing for the outer or rear end of the pointer-setting shaft 14:, the other end of said shaft having its bearing in the back B of the clock. The bell is mounted on the standard or bridge 13 and preferably held in place by means of the screws 15. The said bell is centrally perforated to permit the setting-shaft to extend through the same, as shown. The said setting-shaft is provided near its front end with a pinion 16 (indicated in broken lines in Fig. 3) and just inside of the bridge with a shoulder or projection 17 to limit the endwise movement of the said shaft in the rearward direction. On the outer or rear end of the settingshaft is a turn-button or knob 18, held in place in anypropermanner-as, for example, by the nut 19. twill readily be seen that turning thepointersetting shaft will, through the pinions 9 and 16, turn the center shaft 8 for setting the hands. By having the settingshaft supported in the back of the clock and abridge it is detachable from the rest of the movement with the said back without removing the said shaft from its bearings. By mounting the said setting-shaft concentric with the bell and projecting at the rear thereof I avoid crowding the parts at the back and bring the said shaft into a convenient position for operation wholly out of the way of all other parts.

lVhile not particularly of this invention, I may say that other parts shown in Fig. 1 are the revolving hammer 20, alarm and time winding devices 21 and 22, and alarm-setting device 23.

I claim as my invention- 1. In a clock, the combination of the back of the clock with the center shaft extending rearwardly through said back and having a pinion at its rear end, the bridge or standard mounted on the rear of said back, and the pointer-setting shaft having one bearing in the said back and its other bearing in the said bridge and provided with a pinion and turnbutton, substantially as described.

2. In a clock, the combination of the back of the clock with the center shaft extending rearwardly through said back and having a pinion at its rear end, the bridge or standard mounted on said back at its rear, the pointersetting shaft mounted in the said bridge and back and having the pinion and turn-button, and a bell mounted 011 the said bridge concentrically with the said setting-shaft with the turn-button of the said shaft at the rear of the said bell, substantially as described.
